Facter reports wrong Windows build

Facter 3 load ntoskrnl.exe and calls RtlGetVersion to get the build number.

It seems like build 1909 of Windows has a bug that retrieves 18362 instead of 18363 as the build number.

Loading Ntdll.dll exposes the same method as ntoskrnl.exe and it seems to return the correct build number.

We need to update Facter 3 to use Ntdll.dll instead of ntoskrnl.exe
